GEORGE E. CARTER, OF APEX, NORTH CAROLINA.

DOOR-CHECK.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed. October 7, 1914. Serial No. 865,528.

To all whom it may concern Be it known that I, Gnomes-E. CARTER, a citizen of the United States, residing at Apex, in the county of Vake and State of -North Carolina, have invented certain new and useful Improvements in Door-Checks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in door checks and has for its primary object to provide simple and effective means that will prevent doors being slammed and will eliminate a great deal of noise had in connection with the opening and closing of doors.

An object of importance is to provide a check of the character described that is of extremely simple construction and will oper ate in a reliable manner to cushion a door at the time of closing thereof without making an objectionable sound or injuring the door in any manner.

Another object is to improve devices of the character described so as to render them more practical, reliable and eflicient in oper ation and inexpensive to manufacture.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims.

lVith reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts,

Figure 1 is a fragmentary front elevation of a. door and frame showing my check in use, Fig. 2 is a horizontal sectional view showing a fragmentary portion of a door and frame, and my improved check attached thereto and in operative position in dotted lines, and Fig. 3 is a detail plan view of my improved check showing the frame therefor in section.

Referring to the drawings by characters of reference, A designates as an entirety, a door hinged as at B within a suitable ordinarily constructed frame C.

My improved check is designated D as an entirety and is connected with the frame and door as clearly shown in Fig. 2.

My improved check consists of an inverted U-shaped metallic frame 1 that has its body portion extended on one side to provide a flange 2 that is apertured and has a suitable fastening element inserted therethrough and into the door frame C. The inverted U- shaped frame 1 is secured with its ends downmost at a point intermediate the ends of the upper horizontal part of the door frame C and mounted transversely within the frame in the arms thereof is a pivot pin 3 which has loosely mounted thereon a check block 4. The block 4 is substantially rectangular and has its inner end and a part of one side beveled as at 5 disposed innermost with relation to the door A. The pivot 3 is inserted through the block adjacent to the upper beveled end 5 thereof.

Mounted within an opening formed in the lower end of the block 4 and held therein by suitable fastening elements 6 is a helical expansive spring 7 that projects beyond the lower edge of the block and has fixed upon its outer end a resilient cushion tip 8 that may be formed of rubber or any other suitable material. This tip 8 is of greater diameter than that of the spring 7 and engages the door A upon the closing of said door.

A helical spring 9 is .mounted upon the pin 3 and is secured at one end in any suitable manner to one of the arms of the frame and has its other end disposed in engagement with the beveled face of the block 4. When the block 4 is in normal position, the spring 9 isrelieved of tension, but when the .block is raised to the dotted line position, shown in Fig. 2, the spring will be placed under tension and when the block is released will cause the same to quickly spring back into normal position after the checking action has taken place.

The upper end of the block 4 or beveled end thereof is recessed as at 10 upon one side thereof and secured upon the frame C and projecting through the body portion of the frame 1 is a stop pin or similar element 11 that projects into the space formed by the recess 10 and is designed to engage the front face of the block 4 upon the movement of said block from vertical to horizontal position when a checking action takes place.

This pin 11 limits the movement of theblock 4 and insures proper checking of the closing of the door.

Mounted upon the door A so as to engage the upper end of the block 4 at a point above the pivot pin 3 is a trip 12 that consists of a relatively straight shank portion 13 which extends outwardly from the door and has its outer end formed with a right angularly extending engaging portion 14. This shank 13 extends in a horizontal plane and has its inner end formed with a vertically extending portion 15 which has formed on its free end an eye 16. A screw or other suitable fastening .element 17 is inserted through the eye and into the door A to secure the trip 12 to the door. The trip is arranged so that it will engage the block adjacent to the extreme upper end thereof so as to cause it to move from vertical into horizontal position and bring the tip 8 on the spring 7 into engagement with the door A.

In use when the door A is closed and the trip 12 engages the block 4, the block is moved into horizontal position as shown in dotted lines in Fig. 2 and the element 8 engages the door. The member 8 deadens upon contacting of the door with the check and the spring 7 yieldingly permits inward movement to the door and provides the de sired checking action. The spring 9 quickly moves the block 1 back into normal position after a checking operation and prevents swinging of the member 4 upon the pin. The stop pin 11 prevents derangement of the device and limits the movement of the block to horizontal position as shown in Fig. 2 in the drawings.

What is claimed is 1. A door check consisting of an inverted substantiallyv U-shaped frame secured upon the upper part of a door frame, a pin having its opposite ends secured to the side of the frame, an elongated check block pivoted within the frame on said pin and held in vertical position when the door is opened, a cushioning element secured upon the lower end of the block, a trip member adapted to be secured upon a door and engage and move said block into horizontal position upon the closing of the door so as to cause the cushioning member to engage the door, a spring surrounding the pin and interposed between the block and one side of the frame and having one end secured to the adjacent side of the frame and its opposite end secured to the block to normally hold said block in a vertical position and to prevent the same from swinging idly upon said pin.

2. A door check consisting of a supporting frame secured to a door frame, an elongated check block pivoted within the frame and normally lying in a vertical position when the door is opened, a trip member adapted to be secured upon a door and engage and move said block in a horizontal position when the door is closed, and means secured to said door franle to engage said block to limit the upward movement thereof.

3. A door check consisting of' an inverted substantially U-shaped frame secured upon the upper portion of a door frame, an elongated check block pivoted within the frame, a trip member adapted to be secured upon a door and engage and move said block upward, the upper end of said block being cut away adjacent to one side thereof, and a stop pin carried by the frame and projecting downwardly into the cut away of said block to engage and limit the upward movement of said block.

In testimony whereof I aflix my signature in presence of two witnesses.

. GEORGE E. CARTER.
